在xsd文件上使用ReadXmlSchema时出错。 [英] Error using ReadXmlSchema on a xsd file.
问题描述
我正在使用gotdotnet中的一些示例代码来创建来自
xsd架构的DataSet映射。我正在解决这个错误。代码和错误如下。我可能会提到
还有一个带有这个文件的publictypelibrary文件，我可能不得不以某种方式在
中使用它。我是XML的新手，所以一些例子或文章会有所帮助。
错误是：
Undefined complexType' 'http://www.adsml.org/typelibrary/1.1:MLItemType''是
用作复杂类型扩展的基础。
代码是：
进口系统
进口System.IO
进口System.Xml
部分类_Default
继承System.Web.UI.Page
将myLoadSchema调暗为字符串
将myXmlDataDocument调暗为XmlDataDocument
受保护的子页面_Load （ByVal sender As Object，ByVal e As
System.EventArgs）处理Me.Load
myLoadSchema = Request.MapPath（" BookingsMain-AS.xsd" ;）
''此文件也包含此文件Bookings-PublicTypeLibrary-AS.xsd
运行（myLoadSchema）
结束子
公共子运行（ByVal args为字符串）
尝试
myXmlDataDocument =新的XmlDataDocument （）

I am using some sample code from gotdotnet to Create DataSet mappings from a
xsd schema. I am geting this error. code and error below. I might mention
there is also a publictypelibrary file with this file I may have to use it in
some way. I am very new at XML so some examples or articles would be helpfull.
The error is:
Undefined complexType ''http://www.adsml.org/typelibrary/1.1:MLItemType'' is
used as a base for complex type extension."
The code Is:
Imports System
Imports System.IO
Imports System.Xml
Partial Class _Default
Inherits System.Web.UI.Page
Dim myLoadSchema As String
Dim myXmlDataDocument As XmlDataDocument
Protected Sub Page_Load(ByVal sender As Object, ByVal e As
System.EventArgs) Handles Me.Load
myLoadSchema = Request.MapPath("BookingsMain-AS.xsd")
''This file was also with this file Bookings-PublicTypeLibrary-AS.xsd
Run(myLoadSchema)
End Sub
Public Sub Run(ByVal args As String)
Try
myXmlDataDocument = New XmlDataDocument()
Response.Write("Creating an XmlDataDocument ...")
ParseSchema(args)
DisplayTableStructure()
Catch e As exception
Response.Write("Exception: " & e.ToString())
End Try
End Sub
'' Loads a specified schema into the DataSet
Public Sub ParseSchema(ByVal schema As String)
Dim myStreamReader As StreamReader = Nothing
Try
myStreamReader = New StreamReader(schema)
Response.Write("Reading Schema file ...")
''*************
myXmlDataDocument.DataSet.ReadXmlSchema(myStreamRe ader)
''********Error is here in the ReadXmlSchema
Catch e As exception
Response.Write("Exception: " & e.ToString())
Finally
If Not myStreamReader Is Nothing Then
myStreamReader.Close()
End If
End Try
End Sub
'' Displays the DataSet tables structure
Private Sub DisplayTableStructure()
Response.Write(" ")
Response.Write("Table structure")
Response.Write(" ")
Response.Write("Tables count=" &
myXmlDataDocument.DataSet.Tables.Count.ToString())
Dim i, j As Integer
For i = 0 To (myXmlDataDocument.DataSet.Tables.Count - 1)
Response.Write("TableName=''" &
myXmlDataDocument.DataSet.Tables(i).TableName & "''.")
Response.Write("Columns count=" &
myXmlDataDocument.DataSet.Tables(i).Columns.Count. ToString())
For j = 0 To (myXmlDataDocument.DataSet.Tables(i).Columns.Count
- 1)
Response.Write(Strings.Chr(9) & "ColumnName=''" &
myXmlDataDocument.DataSet.Tables(i).Columns(j).Col umnName & "'', type = " &
myXmlDataDocument.DataSet.Tables(i).Columns(j).Dat aType.ToString())
Next
Response.Write(" ")
Next
End Sub
End Class

推荐答案
嗨Jerry，
您收到此错误消息，因为您的架构可能正在引用
另一个。您的架构中未定义此类型。您能在这里发布
您的架构内容吗？或者，如果您指向此代码示例的
gotdotnet网址会更好。谢谢！

Hi Jerry,
You''re getting this error message, because your schema might be referencing
another one. This type is not defined in your schema. Could you please post
your schema content here. Or it will be better if you point me to the
gotdotnet URL for this code sample. Thanks!

Kevin，
感谢您的回复。
我认为你对引用另一个文件的模式是正确的。
是发行版中的两个文件。我已经通过电子邮件向您发送了这两个文件。一个
的文件在文件名中有typelibrary（这是一个线索）。现在
问题是如何使用这些文件从XSD文件创建数据集
，因为有两个文件。我也认为这个文件中可能有一组模式
。我怎么知道这个文件是如何构建的。
谢谢

Kevin,
Thank you for the reply.
I think you are correct about this schema referencing another file. There
are two files in the distribution. I have emailed you both of the files. One
of the files has typelibrary in the filename ( this is a clue). Now the
question is how do I use these files to create the dataset from the XSD files
since there are two files. I also think there may be a collection of schemas
in this file. How do I find out how this file is constructed.
Thank you
Jerry
